The following commit has been merged in the master branch: commit ef3a409391f55ad0bddbf017d4d4987b783a3059 Author: Antonio Quartulli <ordex(a)autistici.org> Date: Wed May 9 09:50:45 2012 +0200 batman-adv: use DBG_ALL in log_level sysfs definition Each time a new log level is added the developer must change either the DBG_ALL enum definition and the hard coded value in the bat_sysfs.c for the log_level attribute max value. This is extremely error prone. With this patch the code directly uses DBG_ALL in the sysfs definition Signed-off-by: Antonio Quartulli <ordex(a)autistici.org> Signed-off-by: Sven Eckelmann <sven(a)narfation.org> diff --git a/net/batman-adv/bat_sysfs.c b/net/batman-adv/bat_sysfs.c index 62f4f6c..dc1edbe 100644 --- a/net/batman-adv/bat_sysfs.c +++ b/net/batman-adv/bat_sysfs.c @@ -445,7 +445,7 @@ BAT_ATTR_SIF_UINT(gw_sel_class, S_IRUGO | S_IWUSR, 1, TQ_MAX_VALUE, static BAT_ATTR(gw_bandwidth, S_IRUGO | S_IWUSR, show_gw_bwidth, store_gw_bwidth); #ifdef CONFIG_BATMAN_ADV_DEBUG -BAT_ATTR_SIF_UINT(log_level, S_IRUGO | S_IWUSR, 0, 15, NULL); +BAT_ATTR_SIF_UINT(log_level, S_IRUGO | S_IWUSR, 0, DBG_ALL, NULL); #endif static struct bat_attribute *mesh_attrs[] = { -- LinuxNextTracking

The following commit has been merged in the master branch: commit 75c5a2e788ab02f67931442e8dcbc854ae7252d1 Author: Matthias Schiffer <mschiffer(a)universe-factory.net> Date: Tue May 8 22:31:57 2012 +0200 batman-adv: fix locking in hash_add() To ensure an entry isn't added twice all comparisons have to be protected by the hash line write spinlock. This doesn't really hurt as the case that it is tried to add an element already present to the hash shouldn't occur very often, so in most cases the lock would have have to be taken anyways.

The following commit has been merged in the master branch: commit beeb96a4142180c34ddf592aef5a278c2d676bf0 Author: Matthias Schiffer <mschiffer(a)universe-factory.net> Date: Sat May 5 17:51:53 2012 +0200 batman-adv: fix visualization output without neighbors on the primary interface The primary entry and the corresponding secondary entries are missing when there are no neighbors on the primary interface. This also causes the TT entries to miss and makes nodes with multiply secondary interface fall apart since there is no way to see they are related without a primary entry. Fix this by always emitting a primary entry.
